"If I had hold of that I could pull myself out," Teddy said. "See if you can reach it to me, Jan."
After two or three trials his sister did this. Then, holding to a loose end of the grapevine while the other end was twined fast round a tree, Teddy pulled himself out of the hole. Once on firm ground he made the loose end of the grapevine fast to a stone that lay near the edge of the hole.
"What made you do that?" asked Janet.
"So the next time I get down there I can pull myself out," Teddy answered.
"Are you going down there again?" Jan queried.
"Course I am!" declared Ted. "I didn't half look in the cave. It's a big place. I could see in only a little way, 'cause it was so dark. I'm goin' to tell grandpa and have him bring a lantern."
Grandpa Martin was surprised when Ted and Jan told him what they had found in the woods.
"I didn't suppose there was a cave on the island," said the farmer. "I must have a look at it."
"And may I come? And will you take a lantern?" asked Teddy eagerly.
"Well, yes, I guess so," said grandpa slowly.
